worktree

worktree.guessRemote
If no branch is specified and neither -b nor -B nor --detach is used, then git worktree add defaults to creating a new branch from HEAD. If worktree.guessRemote is set to true, worktree add tries to find a remote-tracking branch whose name uniquely matches the new branch name. If such a branch exists, it is checked out and set as "upstream" for the new branch. If multiple matches are found, the command fails. If no such match can be found, it falls back to creating a new branch from the current HEAD.

worktree.useRelativePaths
Link worktrees using relative paths (when “true”) or absolute paths (when “false”). This is particularly useful for setups where the repository and worktrees may be moved between different locations or environments. Defaults to “false”.

Note that setting worktree.useRelativePaths to “true” implies enabling the extensions.relativeWorktrees config (see linkgit:git-config[1]), thus making it incompatible with older versions of Git.
